Answer:
First off 78+92+85=255 so yeah its not 300. Plus 300 is no where near 100, but yes three 100s is 300.
Step-by-step explanation:
Sin+cos=90
49+cos=90
cos=41
There is a 35% chance the first one will not work, and a 49% the second one will not work. (Theoretically there is an 81% chance neither of them will work.)
The value of x is 23 and the value of y is -6
x = 23
y = -6
You're welcome.
